在学习制作文件时，我偶然发现了这个错误，我的老师似乎无法为我指出正确的方向。搜索并阅读了几个相关问题后，我似乎仍然看不到答案。令我惊讶的是我在 NetBeans 中没有出错。

生成文件：

connect4: connect4.o basicBoardFunctions.o evaluationOfBoard.o hashCoding.o iaMinMaxing.o manageInput.o manageInputGeneral.o connect4.o
    gcc -o connect4 connect4.o basicBoardFunctions.o evaluationOfBoard.o hashCoding.o iaMinMaxing.o manageInput.o manageInputGeneral.o connect4.o

connect4.o: connect4.c
    gcc -c connect4.c

basicBoardFunctions.o: basicBoardFunctions.c 
    gcc -c basicBoardFunctions.c

evaluationOfBoard.o: evaluationOfBoard.c
    gcc -c evaluationOfBoard.c 

hashCoding.o: hashCoding.c
    gcc -c hashCoding.c 

iaMinMaxing.o: iaMinMaxing.c 
    gcc -c iaMinMaxing.c

manageInput.o: manageInput.c
    gcc -c  manageInput.c

manageInputGeneral.o: manageInputGeneral.c
    gcc -c manageInputGeneral.c

clean:
    rm connect4.o basicBoardFunctions.o evaluationOfBoard.o hashCoding.o iaMinMaxing.o manageInput.o manageInputGeneral.o tests.o connect4.o

我得到的错误：

gcc -o connect4 connect4.o basicBoardFunctions.o evaluationOfBoard.o hashCoding.o iaMinMaxing.o manageInput.o manageInputGeneral.o connect4.o
connect4.o: In function `main':
connect4.c:(.text+0x0): multiple definition of `main'
connect4.o:connect4.c:(.text+0x0): first defined here
connect4.o: In function `getInputSource':
connect4.c:(.text+0xea): multiple definition of `getInputSource' 
connect4.o:connect4.c:(.text+0xea): first defined here
connect4.o: In function `startGame':
connect4.c:(.text+0x1a9): multiple definition of `startGame'
connect4.o:connect4.c:(.text+0x1a9): first defined here
connect4.o: In function `anounceWinner':
connect4.c:(.text+0x2ac): multiple definition of `anounceWinner'
connect4.o:connect4.c:(.text+0x2ac): first defined here
collect2: ld returned 1 exit status

所有这些函数只在主文件“connect4.c”中定义一次，该文件不包含在任何地方。我不知道该尝试什么，但我认为这对受过训练的人来说可能是显而易见的。我觉得我会受到很多批评，但我认为其他情况不适用于我。

问题在于双链接相同的目标文件connect4.o：

connect4: connect4.o ... connect4.o
    gcc -o connect4 connect4.o ... connect4.o

删除其中一个文件，一切都会好起来的：

connect4: connect4.o ...
    gcc -o connect4 connect4.o ...
